  2. Climate of Mars - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Mars

    Current research suggests that Mars is in a warm interglacial period which has lasted more than 100,000 years. [134] Because the Mars Global Surveyor was able to observe Mars for 4 Martian years, it was found that Martian weather was similar from year to year. Any differences were directly related to changes in the solar energy that reached Mars.

  3. Martian polar ice caps - Wikipedia

    en.wikipedia.org/wiki/Martian_polar_ice_caps

    1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...

  4. Astronomy on Mars - Wikipedia

    en.wikipedia.org/wiki/Astronomy_on_Mars

    Eventually, in the far future, the length of a day on Earth will equal and then exceed the length of a day on Mars. As on Earth, Mars experiences Milankovitch cycles that cause its axial tilt (obliquity) and orbital eccentricity to vary over long periods of time, which has long-term effects on its climate. The variation of Mars's axial tilt is ...

  5. Water on Mars - Wikipedia

    en.wikipedia.org/wiki/Water_on_Mars

    [3] [12] [13] No evidence of present-day liquid water has been discovered on the planet's surface because under typical Martian conditions (water vapor pressure <1 Pa [14] and ambient atmospheric pressure ~700 Pa [15]), warming water ice on the Martian surface would sublime at rates of up to 4 meters per year. [16]

    The idea of transforming Mars into a world more hospitable to human habitation is a regular feature of science fiction. Scientists are now proposing a new approach to warm up Earth's planetary ...

  7. Atmosphere of Mars - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Mars

    To explain the coexistence of liquid water and faint young Sun during early Mars' history, a much stronger greenhouse effect must have occurred in the Martian atmosphere to warm the surface up above freezing point of water. Carl Sagan first proposed that a 1 bar H 2 atmosphere can produce enough warming for Mars. [45]

    en.wikipedia.org/wiki/Evidence_of_water_on_Mars...

    Seasonal flows on warm Martian slopes (also called recurring slope lineae, recurrent slope lineae and RSL) [3] [4] [5] are thought to be salty water flows occurring during the warmest months on Mars. Indeed, there is much photographic and spectroscopic evidence that water does today flow on parts of Mars.
